Overview
The TMUX1122DGKR is a dual-channel analog switch manufactured by Texas Instruments, designed for low-voltage signal routing applications. It operates on a single supply voltage ranging from 1.08 V to 5.5 V and features an ultra-low on-state leakage current of 3 pA. The device provides a maximum on-resistance of 4 ohms with a channel-to-channel matching of 10 milliohms. Packaged in an 8-pin VSSOP (DGK) format, it supports a continuous DC switch current of 30 mA. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low leakage current minimizes signal distortion in high-impedance circuits
- Low on-resistance ensures minimal signal attenuation during transmission
- Compact surface-mount package facilitates dense PCB layout designs
Applications
- Portable medical instrumentation signal conditioning
- Automotive sensor interface modules
- Industrial process control data acquisition systems
Procurement Notes
Verify the specific ordering suffix against official Texas Instruments documentation to confirm pin configuration and packaging details. Ensure compatibility with standard reflow soldering profiles for VSSOP packages. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when designing circuits requiring precise analog signal switching with minimal power consumption. The low operating voltage range suits battery-powered devices. Verify that the required channel count and package size align with the system constraints. Consider thermal management requirements if operating near the upper temperature limits.
Part Context
This part belongs to the TMUX11xx family of low-power analog switches. It shares core electrical characteristics with other members like the TMUX1121 but differs in channel configuration and package type. The DGKR suffix indicates a specific reel-based tape and reel packaging variant suitable for automated assembly processes.
Replacement Considerations
Direct substitutes include the TMUX1121DGKR for identical performance in a single-channel configuration or the TMUX1122PWR for a TSSOP-16 package alternative. Verify pinout compatibility and thermal dissipation capabilities when transitioning between different package styles within the same product family.
